Acetylene gas, C2H2 undergoes combustion to form carbon dioxide and water in the balanced equation

a) What mass of carbon dioxide will be produced if 4.00L of oxygen reacts with 6.3kg of acetylene?

b) What reactant is the limiting reactant? How do you know?

Using the data provided, calculate the density of the liquid to the correct number of significant figures.

Mass of 10 mL Empty Graduated Cylinder = 26.033 g

Mass of 10 mL Graduated Cylinder and Liquid = 30.885 g

Volume of Liquid in Cylinder = 5.20 mL

OA. 2.91 g/mL

OB. 0.933 g/mL

OC. 5.94 g/mL

OD. 0.168 g/mL

OE. 1.07 g/mL

R - tongue rolling

r - non-rolling

F - free earlobes

f - attached earlobes

Using the punnett square (RrFf x RrFf), what fraction of the offspring will be tongue rollers and have free earlobes?

I know the answer which is 9/16, but I do not understand.

Please explain.

1) Calculate the molarity of hypochlorite ion in a commercialbleach solution. It contains 5.25% sodium

hypochlorite by mass and the density ofthe solution is 1.08g/mL.

2) Calculate the molarity of hypochlorite ion when 1.00mL ofcommercial bleach is added to 25.00mL

of dye solution.

Please go through step by step and include units.
